Abstract

Electromagnetic field (EMF) at a frequency of 24 or 14 MEGC and intensity of 400 or 200 V/m, increases numbers of hepatocytes from rats with chromosomal aberrations 1.4-1.5-fold. The magnitude of the response does not appear to change with the increase in the field intensity EMF at the above frequencies and intensity of 100 V/m does not cause any cytogenetic effects. No such effects were notable with EMF-frequency of 4 MEGC.

Main findings

Exposure to EMF at 24 or 14 MEGC with intensities of 400 or 200 V/m increased the number of rat hepatocytes with chromosomal aberrations by 1.4–1.5-fold. The response magnitude did not appear to change with increased field intensity at these frequencies; 100 V/m at these frequencies produced no cytogenetic effects, and no effects were observed at 4 MEGC.
